Have tried latest 2 versions of Aida64 plus a beta and all give same result, so not sure if it is Aida64 itself or the latency is actually worse, but after a clean boot, and at any point before PC is put into sleep, latency is 73-76 ns, but after a resume from sleep, it jumps to 130-140 ns, with bandwidth numbers being roughly equal as before.
1401 mb bios, 285K CPU, 2 sticks G.Skill ram 64gb total, either at XMP or other frequencies - no change in this issue. Earlier MB bios had same issue...
Any thoughts?

I had this problem. Had to disable Intel Speed Shift. Partly looks like a BIOS bug, as performance before after suspend should be the exact same. Many other BIOS bugs and many more months to resolve.

Yep - you nailed it. That's it. I'll have to research Speed Shift a bit...
Thanks for your help!

Great. Hopefully the BIOS dev team reads this forum. Lots of things to fix that still haven't been addressed in past BIOS updates.

I did notice thought that disabling Speed Shift shows "Current/EDP limiting", "MB VR Throttling" and "Thermal Throttling" all as being yellow and "Yes" in Intel XTU OC / monitor app. They all 3 just stay activated like that, even though temps and loads are at idle. CPU voltages look the same with SS on or off to me, so maybe it's just a bug in XTU - not sure, but turning SS back ON shows the proper display for those things in XTU.
Who knows, but as you said, I guess lots of things still to address. What are some of the others that you've found?
Thanks.

Same behavior for me with XTU uninstalled. Had to uninstall XTU since it was unstable.

Other issues: restoring verbose boot screen preference, CUDIMM stability (present and future), poor stability of non-XMP settings, insane number of reboots with no heads up after tweaking memory settings.
